To all whom it may concern.-

Be it known that I, CARL J. EHBETs, of Hartford, in the county ofHartford and State of Connecticut, have invented new Improvements inRevolvers; and I do hereby declare the following, when taken inconnection with accompanying drawings and the letters of referencemarked thereon, to be afull, clear, and exact description of the same,and which said drawings constitute part of this specification andrepresent, in-- Figure 1, a sectional side view of so much of a revolveras will illustrate the invention, and showing the hammer in its forwardposition; Fig. 2, sameside view, showing thehammer in its extreme rearposition; Fig. 3, top,

view, looking down upon the hammer and showing the hinge-joint betweenthe nose and body portion. This invention relates to an improvement inrevolving fire-arms, with special reference to the hammer. In the moregeneral construe tion of revolvers, the hammer extends .up through theframe, and is provided with a thumb-piece, by which, if occasionrequires, the hammer may be turned. Accidents fre quently occur in theuse of these arms, due chiefly to the exposure of this projecting partof the hammer. If in the usual construction of hammer the thumb piece.or; extension be dispensed with it isimpractical to inclose the hammerwithin the frame-as, for illustration, the are described by the nose ofthe hammerturning upon its pivot would be as indicated in broken line,Fig. 1. To increase the-extent of the frame so as to permit this are tobe described within it would not only make the frame cumbersome, butwould detract materially from the graceful appearance of the arm. I Theobject of my invention is to conceal the hammer and yet permit it toswing upon its pivot in the usual manner; and it consists inconstructing the hammer in two partsabody portion and nose portionthenose part hinged to the body portion of the hammer, so that the nose mayturn upon its hinge in a plane at right angles to the pivot on which thehammer turns, said hammer constructed with an escape from the notch f ofthe hammer.

the frame above the nose-piece, serving to direct thevnose of the hingedportion in its forward movement, as more fully hereinafter described.

A represents the frame of the revolver in the usual shape, except that,instead of the recess within which the operative mechanism is arrangedbeing open at the top, thetop of the recess is closed.

B represents the usual recoil-plate, in which is an opening, a, throughwhich the nose of the hammer may pass to strike the cartridge; 0, thetrigger; I), the body of the hammer hung upon a pivot, I), in the usual.method of hanging the hammer of revolvers. Thehammer is turned rearwardupon its pivot by means of the triggermhich may be connected with-thehammer by any of the usual mechanism for so doing, such mechanismconstituting no part of my present invention.

As illustrated, the hammer is turned by means ofa strut, d, hinged tothc trigger. as at e, and in rear of the pivot of tbetrig'ger,

the upper end or nose of the said strwtarranged to engage a notch, f, onthe hammer forward of its pivot, whereby when the trigger is pulled thehammer is thrown rearward until such time as the strut may escape fromthe notch; then the hammer will fly forward under the reaction of themainspring unless a sear, g, or its equivalent, be arranged to engage anotch on the hub of the hammer, say, when at full-cock, as seen in Fig.2, which engagement occurs just before the strut (2 would In such casethe trigger is constructed with a shoulder, h, which, when thetrigger isfurther pulled, will strike the scar and turn it from its engagementwith the hammer, so that the hammer will escape and be thrown forwardunder the reaction of the mainspriu Instead of making the hammer in asingle piece throughout, the nose portion E is made separate from thebody, hinged thereto above the pivot of the hammer and as at Z, and soas to swing on its pivot in a plane at right angles to the axis or pivoton which the hammer turns, the nose being free to swing upon its hinge Zand so as to be turned from its forward position, as seen in Fi J, tothe posi- IOC . from the nose to the pivot of the hammer is.

contracted by so much as the nose portion is turned toward or approachesthe pivot of the hammer. The nose is provided with thensual point, t, topass through the aperture ain the recoil-plate to strike the cartridge,and has an extension, F, in rear of its pivot.

The top of the recess in which the hammer works is constructed to form abearing, an, against which, when the hammer is in its forward position,the extension F of the hammer will rest, and in so resting the nose ofthe hammer is thrown up to its proper striking-position and there held.

From the bearing-point m in the top of the recess the surface inclinesfrom or is made eccentric to the pivot b of the hammer, andso that asthe hammer is turned backward the projection F may turn outward topermit the nose portion to turn downward, the back of the nose port-ionriding over the bearing on to cause it to thus turn, and the curvatureof the top of the recess in rear of the bearing an should be made sothat the projection F may ride thereon, while the back of the nose-piecerides upon the bearing-point m, and so that the nose-piece will besupported by the two points, one in the rear and the other forward ofits hinge, and thereby be prevented from play. When the hammer has beenthrown back to full-cock, as seen in Fig. 2,, the nose is far below theaperture through which it is to strike. As the hammer escapes from thestrut or from the sear, as the case maybe, under the reaction of themainsprin g, it is thrown forward in the usual manner, and in suchmovement the extension F rides upon the upper surface of the recess andcauses the nose of the hammer to turn forward, until arriving at itsextreme forward position it has reached I the bearing an and the hammeris in its proper position to strike the blow. The connection between thenose-piece and the bodyis simply tglngues on the one setting into agroove in the 0 er,

tongue part should take a bearing on the corresponding edge of the otherpart, so as to V as seen in Fig. 3. The shoulder on the form a strongsupport or connvrl ion between the two in imparting the blow.

Vhile I prefer to govern the movement of the nose portion of the hammerby the top of the recess in the frame, the nosemay be guided in itsforward movement bythe bottom n of the passage to the aperture i, thebottom of this passage being inclined upward and forward toward theaperture, as shown, and so that the point of the hammer may strike thisinclined surface as the hammer is forced forward and ride up thereon,and so as to pass through the aperture.

It will be readily understood that in the class of revolvers in which afiring'pin is employed against which the hammer strikes, the point onthe nose of the hammer in this case will be dispensed with, the hingedportion striking the firing-pin as does the hammerin the usualconstruction. In fact, the operation of the hammer is precisely the sameas that of the hammer of usualconstruction, save only that the noseportion is hinged to permit it to approach the pivot on which the hammerturns in its rear movement, and recede therefrom as it is thrownforward.

I have described and illustrated my invention as applied to a revolver,and it is to this class of fire-arms to which in y invention isparticularly adapted; but it may he applied to other arms in which aconcealed hammer is desirable.

I claim- The combination of the body portion D, and the nose portion E,hinged thereto above the pivot on which the hammer tums, and so as toswing in a plane at right angles to the pivot on which the hammer turns,the said nosepiece constructed with an extension, F,in rear of its hinge-pivot, the recess in the frame constructed with a bearing, m,'abovethe nosepiece, and in rear of the hinge-pivot when the hammer is in itsforward position, and against which the extension F will strike, withmechanism substantially such as described, to turn the said haunncr uponits pivot, substantially as specified.
